abstract = {We present a new lattice formulation of chiral effective
field theory interactions with a simpler decomposition into
spin channels. With these interactions the process of
fitting to the empirical scattering phase shifts is
simplified, and the resulting lattice phase shifts are more
accurate than in previous studies. We present results for
the neutron-proton system up to
next-to-next-to-next-to-leading order for lattice spacings
of 1.97, 1.64, 1.32, and 0.99fm. Our results provide a
pathway to ab initio lattice calculations of nuclear
structure, reactions, and thermodynamics with accurate and
systematic control over the chiral nucleon-nucleon force.},
